Error: HTTP Error: 429, Quota exceeded for quota group 'ReadGroup' and limit 'CLIENT_PROJECT-100s' of service 'cloudresourcemanager.googleapis.com' for consumer 'project_number:563584335***'.

when I tried to deploy functions using firebase-cli

firebase deploy --only functions --token $FIREBASE_TOKEN

I changed the value of FIREBASE_TOKEN thinking that it might have expired. deploy worked for one time after changing token but then again cli tools again started giving above error. Also, I checked quotas but couldn't find any value that exceed the quota limit. My project is on blaze plan (pay as you go).

Maybe I'm missing something? Could anyone help me out on when exactly this error comes and how to fix it?
